SET_SW

TIMEFUNC

supports the summertime/wintertime changeover in CPUs that do not have the time status. For this purpose it sets the CPU clock to the current time and according to the changeover rules in the Control DB.

FB 61

SET_SW_S

TIMEFUNC

supports the summertime/wintertime changeover in CPUs that do have the time status. For this purpose it sets the time status to the current time and according to the changeover rules in the Control DB.

FB 62

TIMESTMP

TIMEFUNC

transfers the time-stamped messages of an IM153-2 into its instance DB.

FC 60

LOC_TIME

TIMEFUNC

reads the time status or time of the CPU and calculates the local time. It is therefore only useful on CPUs with time status.

FC 61

BT_LT

TIMEFUNC

calculates the local time from the base time given at the input.

FC 62

LT_BT

TIMEFUNC

calculates the base time from the local time given at the input.

FC 63

S_LTINT

TIMEFUNC

sets the required time interrupt to the preset time. This time is given in local time.
